Description
CelliMax® Versa Medium is a chemically defined (CD) basal medium for CHO cells, free of animal-derived components and hydrolysates; contains no L-glutamine and no phenol red. Used with the CelliMax® feed media, it supports high-density growth of CHO cell lines and enhances protein expression. Manufactured by our partner CelluPro and supplied in the EU by SeamlessBio.
Key features
- Chemically defined, animal-component-free and hydrolysate-free
- Cell lines: CHO-K1, CHO-DG44, CHO-S and GS-knockout CHO lines
- Applications: cell thawing, passaging, fed-batch culture and cryopreservation
- Powder format for in-house preparation at any scale
- No L-glutamine included – add L-glutamine or a stabilised dipeptide according to your cell line and process
